Aaron Poreda won’t be inserted in the starting rotation

And then there’s Poreda, the hard-throwing left-hander who was the team’s top pick in the 2007 First-Year Player Draft. He has become an instant bullpen presence with a 0.90 ERA over eight games, but don’t look for him to be stepping back into the role he held so well to the tune of a 2.38 ERA over 11 starts at Double-A Birmingham at the outset of the 2009 campaign.

“Poreda is a reliever right now, and it’s unfair to him for me to start him,” said White Sox pitching coach Don Cooper. “He’s long since been stretched out. He’s getting over the hump and showing he’s a quality left-handed reliever. We don’t want to pull the plug on that.”
